BATH-TRAP CAP AND PIPE.

I 7 Application filed February 6, 1903. Serial No. 142,169. (No model.)

To all whom, it may concern.-

Be it known that I, HENRY J. LUFF, a citizen of the United States, residing at Cleveland, in the county of Ouyahoga and State of Ohio, have invented certain new and useful Improvements in Bath-Trap Caps and Pipes; and I do declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to bath-trap caps and pipes; and the object of the invention is to provide means for positively supporting the pipes and caps of bath-traps, all substantially as shown and described,and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a perspective view of a section of floor and a screw-cap for the trap shown as in position thereon, and Fig. 2 is a sectional elevation of said cap and the associated parts as embodied in my invention. Fig. 3 is a cross-section of the hard-metal collar, and Fig. 4 is a side elevation of the trap with which my invention is adapted to be used.

Hitherto and universally, so far as I know and believe, it has been customary to set bath-traps with caps attached directly to or upon the upper end of the pipe which contained the trap, as pipe A in this instance forming part of the trap, and the said pipe was left wholly without any support whatever about its top or upper portion. This left the pipe liable to be more or less seriously injured when it was necessary to remove the cap therefrom to get at the trap, if, indeed, it was not twisted so as to renderit useless thereafter, and there was danger, too, of the pipe dropping or being pushed down when the support from below became accidentally displaced or broken, and such accidents have been very common.

My invention is designed more especially to remedy these defects and to materially improve the construction, and to these ends I provide the usual lead pipe A of the upper portion of the trap with a brass or other comparatively hard-metal collar B, which is sol- O and flange 2 of the collar to make a sealed connection. It follows from this construction that the soft and easily-twisted lead pipeAis relieved from all possible strain and danger when cap O is to be removed and that the end of pipe A is otherwise provided with a definite supupport of its own regardless of all other means of support hitherto or commonly used and which in any event holds said pipe in a fixed relation to the floor and to or with the lower connections, whatever they may be. This renders impossible the twisting of the trappipe as formerly and also sustains it against possible dropping away from the floor and its connections at that point when the under supports happen to get knocked out.

It will be noticed that the pipe A extends above floor F the depth of collar B, so as to bring the connections and supports wholly above or upon said floor. If a false floor or support across from the joists were used in lieu of the main-floor, the construction would be the same.

What I claim is 1. A bath-trap and a collar permanently secured about its upper end having a flange horizontally adapted to be fastened to a floor, thereby fixing the pipe in respect to said floor and preventing the twisting of the pipe, said collar having a threaded neck, and a cap screwed onto said collar overlapping the horicured to the floor, and a cap screwed upon Zontal flange thereof, substantially as desaid flange, substantially as described.
